越南采购需求：U型螺栓、不锈钢螺栓、铁轨材料、锚、电镀、铆钉

I am looking for a quotation for a specific type of rivet manufactured in Vietnam. The rivets should be unpainted and feature a countersunk design. Please provide details on pricing, minimum order quantities, and lead times for this product, as well as any other relevant information that could assist in making a decision. Additionally, it would be great to know about your production capabilities and whether you offer customization options. Any catalogs or specifications you could share would also be appreciated. Looking forward to your prompt response!
